Why I can’t rotate the inserted OLE image?

Inserting image like this has a problem: when we copy the drawing to others, we will have to attach the image file, otherwise, the image won’t show in the drawing that we send to others. That’s why most of the time CAD users prefer to insert an OLE image since the OLE image is saved in the drawing and there is no need to attach the image again.

Why I’m unable to edit by double-clicking the text? Why I have to choose again after already choosing graphic editing?

By default, CAD supports operations to select objects before executing the command, so many users are accustomed to operating after selecting the graphics that they are going to edit. But this can be changed. You can execute commands first and then select the graphics to be edited.
